` for motor driven vehicles, andmoreispec'ifii ischaracterized not only by the fact thatithe cally is concerned withr the provision of 'a' cheap, l'stron and eiiicient devlc 0f this class particu arly adaptable for use in connection with motor truck wheels of the type y commonly provided with solid-tires.

The non-skid chain hereinafter described chain, which in `use extends from aspoke around the wheel felly and tire, readily may be connected with and vdisconnected from the s oke, but furthermore by the fact that the eective length of the chain readily may be adjusted as occasion may require.

In .the accompanying drawings illustratin my inventiofn,y y

i re 1 is a ra entary view in perspective li a vehicle lieel provided withlthe improved non-skid device of my invention;

ig. v2 is an elevational view of one of the spolge engaging clamps; and

1g. 3 is a perspective view of one ofthe chains and the device for coupling the same to the spoke engaging clamps.

Similar characters of reference refer to similar parts throughout the several views.

In Fig. 1 of 'the drawin trated a portion of a truck w eel comprising the spokes 4--4, felly 5, and solid tire 6. Any desired number of the -wheel spokes, conveniently every alternate spoke, are prof vided with non-skid units each of whichbcomprises a spoke engaging clamp A cham B, and a pair of coup mg devices with the conformation and use of which my present invention is particularly concerned.

Although my present invention is not ar-l ticularly directed to the construction'oI the. spoke engaging clamp, I will say that each `or desirable to shorten,y the effective lengt of the same may comprise the lates 7 7 conformed to receive the spoke c am ed betweenthem. The plates 7-7 of eac spoke en gmg clam are provided with ears 8 8 an are secure together by bolts 9--9 passpeoioation of Lettersletent.

inf-through apertures in the said ears 8-8. A thou h not shown the plates 7-7 may, of course, lined with rubber or other suitable 4 material. The apertures in the ears 8-8, as` well as those portions of thel clamping bolts which engage therein, are desirably given polygonal cross sections so that rather large lat bolt heads 10-10 are held at the inclination shown in Fig. 2, thereby rendering it possible to pass the coupling members C-C throu h ,the bolt head apertures, as will pres` entlye explained. 'Each ofthe spoke engamg clamps just described is ordinarily, alt ough not necessarily( left permanently on the wheel after being positioned as shown spoke engaging clamp A by the coupling de- Vlces C-C, each of'which is in the form of an'integral drop for ing comprising the two hook portlons 13 an 14 separated by the intermediate hump 15.

.The hook portion 13 of each coupling device C is conveniently provided with a sub` 'stantially T shaped extremity 16 which, .while permitting 1nsertion of the hook 13 in the aperture of its associated bolt head 10, eflectuallyA prevents its accidental disengage ment therefrom, the substantially key-hole slot shape of the bolt head aperture and the T shaped extremity of the hook 13 requiring that when the coupling member() is to be disengaged from lts associated bolt head a erture the said coupling be turned to a posltion that it does not assume in the normal useof the non-skid device.

It will be noted that the hook portion 14 of each cou ling device C is designed to receive one o? the end lengths of its associated chain B, the` enlarged extremity 17 of the hook 14 'reventing disengagement of the chain andpcoupling when the hook portion* 13 ,of the latter engages in its associated bolt head aperture. It will be noted, however, that'if for yany reason it becomes necessary]l of one of the'chains- B that it readily may slippingone ori-both of the end mks of t e c ain off the coupling members C by way of the hooks 18 of the aociate chain B from slipping ,up into` the hook portiolil When the device is in use,l

While I have illustrated but` one arrangement for detachably connecting the coupling element Cv ,with the 'spoke engaging'clamps it will b e understood that Ymyinvention'A C011#` templates the use of any suitable arrangenient to accomplish this purpose.

Having thus described lmy vinvention what I claim as 'newand' desire to secure by Let# ters Patent ofv the States is: l

The combination with a chain comprising y n a pluralityv of links, of a coupling' member adapted to be :manipulated thiough of said links, said coupling Ine'i'lber comprislng a shank portion having an extension thtQugh is engaged, the other end of said s 'ank portion being bent upony said shank portion and 1 `peilrig of such size as to pass through said `In witness whereof, I hereunto subscribe my name this 10th` day of July, 1917.
